We're pleased to release Bminer 16.1.0.

* Support for BFC and Cuckatoo32.

At least for the summer.

I run a small farm of ASIC A9 Zmasters and they were heating my shop and giving me a decent profit over the winter but even at $0.06 a KW it will cost me too much to run them through the hot weather. So I'm drinking Bushmill's, smoking a Cuban cigar, and crying a little.

which models tend to fail? 1400W, 1600W?

i am in contact with the manufacturer with the PSU, so please provide me some informations:
How long did the PSU ran without problems 2 weeks/months?
Which model exactly? its written on the stickers
How is your failure rate?

The problem is a failed MOSFET on the secondary, which fails short. Thankfully the PSU has short circuit protection, that's why you hear the click. Check the output with a multimeter, you will likely see a shorted output. If so then the fault is most likely one of these MOSFETs.

This can be repaired pretty easily with a hot air rework station, some experience doing these sort of repairs, and some patience as the MOSFETs are pretty solidly soldered to the board and surrounded by large copper planes. An easy way to check to see which MOSFET failed is to probe between the gate and the drain or source (just use a nearby heatsink); the failed MOSFET will show ~4.4ohms lower, as the working units will pass through two 2.2ohm resistors in series, the failed one will be low impedence to the source and drain. I took a working MOSFET from one failed PSU and transplanted it into another, and now I have a working PSU and another PSU for spares.

Hey, i think you runned two instances same time mby?
